SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 388,818, dated September 4, 1888.

Application tiled March 9, 1888.

To all whom, it may concern:

Be it known that I, LEWIs A. BROWN, of St. Louis, Missouri, have made a new and useful Improvement in Seal-Locks, of which the following is a full, clear, and exact description.

This improvement can be applied to many forms oflocks-to padloeks, trunk-locks, doorlocks, drawer-locks, Sac. It can also be embodied in some forms of car seals.

The features of the improvement are mainly as follows: That part of the padlock or other lock or seal which needs to be reached to elect the unlocking of the lock-bow, bolt, 85e., is adapted to be shielded by a plate which in use is slipped or passed or moved in the lock or seal so as to come over the part in question, and in that position to be locked, and thus for the time being prevent access to that part. The shield in turn is guarded by a stiff sealsuch as a glass plate-and in such manner as to necessitate the breaking ofthe seal in order to reach the shield-fastening. Thus the presence ofthe still' seal intact attests that the lock has not been opened. The seal may have any peculiar shape or color imparted to it and any impression formed in or upon it; o1' any label bearing data may be applied to it, and the label may be applied to the back of the seal.

The most desirable mode of carrying out the improvement is illustrated in the annexed drawings, making part of this specification, in Which- Figure 1 is a front elevation of a padlock having the improvement; Fig. 2,another front elevation, but showing the shield and seal raised from the position in which the seal is inserted in the shield into the position in which the shield is locked and the seal confined so that it must be broken to detach or remove itfrom in front of the shield; Fig. 8, a front elevation of the padlock, its front plate, shield, and seal being removed; Fig. 4, an edge elevation of the padlock; Fig. 5, a section on the line 5 5 of Fig. 1; Fig. 6, a section on the line 6 6 of Fig. 1, and Fig. 7 a View showing the application of the improvement to a trunk or door lock.

The same letters of reference denote the same parts.

A represents the padlock used to illustrate the application. It is of the customary form,

Serial No. 266,725. (Model.)

saving as it is modified by the embodiment therein of the improvement in question.

The spring-catch B, Figs. 1, 3, and 5, is any suitable device for locking thepadlock-bow a.

C represents the part which, I'or convenience, is termed the shield It is adapted to be moved, in the front portion of the padlock, upward and downward, as indicated by its po sitions shown, respectively, in Figs. 1 and 2. At its side edges,and also at its top edge, it is covered by the front plate, a', ol' the padlock in both positions of the shield. It is notched at c, Figs. 1, and 5,to enable the catch B to be reached and detached from the bow a when the shield is in its position of Fig. 1. The shield can,by moving it toward the bow a., be shifted into the position of Fig. 2, in which position the imperforated portion of the shield comes over the catch B, and access thereto is therefore barred. In its first position the shield can be confined within the padlock-case el by allowing its lower end to rest upon the rivets e, which are used to confine the l'ront plate permanently to the case a?. When the shield is moved into its second position, it is for the time being therein held by means of the springcatch D, Figs. 1, 3, and (i, said spring-catch, when the shield is moved to cover the catch B, entering an opening, c', in the shield, sub stantially as indicated.

E represents the seal employed to guard the shield C. When the shield C is in the position of Fig. l, said seal can be applied thereto, and when said shield is shifted to cover the bowfastening the seal is moved therewith so as to confine the edge c, Fig. 6, of the seal beneath the front plate of the padlock-case. At the same time the seal E, by reason of its lower edge, c, resting upon the ange cof the shield, cannot be withdrawn downward, so as at its upper edge, e, to be free of the padloclccase. The shield at c3 c'i may also be extended to furnish an additional support for the seal E; but I desire not to be restricted to any special means for confining the seal E so as to cover the shield-fastening when the shield is in position to cover the bow-fastening, it only being necessary to confine the seal E so that it cannot either be Withdrawn edgewise or sidewise, so as to expose the shield-fastening.

As the seal E is in practice a stift frangible IOO part-such as a glass plate-it is sufficient therefore if any obstacle is interposed against its being withdrawn edgewise, and if the seal at any of its edges is so held that it cannot be moved sidewise away from the face of the shield. The shield also can be modified to suit the position and character ofthe fastening used to retain the bow, bolt, bar, or latch, or other locking part ofthe lock, and the shield fastening can be variously located and constructed, and according to such modifications is the seal E modified in shape and operation.

F, Figs. 5 and 6, represents a label applied to the baek of the plate E.

l claim- The combination of the pad or other lock, the spring-catch B, the shield, notched as described, the springeateh D, and the seal, sub stantially as described.
